T143 series Thyristor

Т143 series thyristor is a phase control thyristor in disc design with pressure contacts. It has a repetitive peak off-state and reverse voltage VDRM/VRRM 400-1800V. Mean on-state current ITAV 400A 500А 630A 800A 1000A 1250A. The thyristor has an industry-standard ceramic housing making it easy to integrate the device into existing equipment. The maximal junction temperature Tjmax is 125 °C.

Phase control thyristors are widely used to control high load with a low control signal applied to the control gate. They can be used in electrical systems for various industries, including AC and DC circuits operating at industry standard or increased frequency. The thyristors have a sealed housing isolating the functional part and the semiconductor element from mechanical impacts and environment. Disc thyristors are notable for the possibility of two-sided cooling.
